cTrader Risk & Reward Charting Tool from ClickAlgo

Hello, I've had a problem with one of your bots since today. What's interesting is that the short position works, but the following error message appears for the long position. And what's even more interesting is that this is currently only in Ger40. In US30, for example, the long and short sides work. What can I do? do you have any idea? It's only in this chart and only in the buyposition. until a few days, i had no problems. are there any imagefolders or something like that to delete?
